Chances of finding a good 216 are slim. Even if you find one as a rebuildable core, it will be much more expensive rebuilding then getting a 235 that will bolt right in. It’s a swap that myself and many other ‘bolters have done. There are plenty of them out there and if you get a 54-55 it’s a direct swap. 56-62 would require a adaptor plate to move the water pump. I performed this installation and it was not hard at all. You’ll also gain HP. MY ‘59 235 has 135 vs the 90 the 216 it came with.
